I have downloaded and installed the latest jet drivers and MDAC 2.8. I have given IUSR access to the HKEY_LOCAL_MACHINE/SOFTWARE/ODBC registry key. I have given IUSR access to the TEMP directory. I have searched all over the internet but I cannot figure out what is wrong. Does anyone have any suggestions or does anyone know a better way to do this? I just want to update an existing Excel file.
